JOHN H. YOUNG, OF SIT. LOUIS, MISSOURI.

PUMP.

Specification of vLetters Patent No. 24,073, dated May 17, 1859.

To all whom 'it may concern:

Beit known that I, JOHN H. YOUNG, 0f St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Liftingand Forcing Pumps; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawing, making a part of this specification, and which represents a vertical central section through the pump.

My invention relates to a double-acting, lifting and suction pump, and consists in the manner in which thevalves are made to act in separate chambers, while they are united to the same stem or rod-tlie chambers being united by a waterway, as will be explained, the object being to have a continuous flow of water through the pump.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

A, represents the pump stock that, eX- tends into the well; B, is an air chamber; C, the nozzle or exit, and D, the brake by which the pump is operated. These may be of any of the well known forms of construction, and need not be more particularly referred to in the description.

Within the pump stock or barrel A, two chambers a, a', are formed by means of a partition or division plate Z2, having in it, one, two, or more valves o, which open upward. The two chambers a, a', are connected by a Waterway E.

F, is the support, in which the pump brake or lever D, is hung. The stem or rod G, is attached to the pump brake D, by means of a link H, at its upper end, while its lower end passes through the plate d, into the tubular opening e, in the cap piece I, of the air chamber, where it is united to the piston rod J, which rod J, is packed as shown by the red lines, so as to work air or water tight in the opening e. f is a plate over said packing to keep it in place. The top plate d, has packing underneath it, as shown also by red lines.

To the piston rod J, is connected by the arms or brackets g, the upper bucket K, which is packed (as shown by the red lines) so as torun freely but tightly in the stock or cylinder A. To this bucket K,`is connected by the arms or brackets 7L, (so as to .and to the lower end of this tube leave free water way between them as there is between the upper arms g), a tube z' which passes through the division plate o, where a tight or packed joint should also be made;

z', is fastened by meansof the arms or brackets j j, the lower bucket L, also packed as shown by the red lines. Through this tube i there passes a stem c, which has upon its upper Vend a valve m, that has a seat against the underside of the bucket K, and on its lower end a valve a, which has a seat on the upper side of the lower bucket L. These valves m, a, may be called puppet valves, for although they move with the buckets, yet they have a motion independent of the buckets, and open and close by the pressure or weight of the water as the case may be.

The stem lc, moves perfectly free through the tube a', no packing being required therein but each valve, though connected to one stem, and moved with the buckets, work in separate chambers, their joint action however tending to move on a continuous iow or column of water through the pump, without allowing it at any time to come to a state of rest. This makes the pump work with great ease to the operator of it, for the column of water is only put in motion once, and when in motion, the power applied to the brake is cumulative, and causes it to flow through with great facility.

0, is a flap valve opening upward, and is designed for holding the water in the pump, when it is at rest, so that it will not have to be refilled each time that the pump is to be used.

p is the passage between the air chamber and nozzle or eXit.

r r, are the openings through the partition plate b, and over which the valves c c, are hung, and s the passage leading from the pump cylinder.

The operation of the pump is as follows, supposing the pump to be filled with waterwhen the buckets are raised, or moved upward the puppet valves m, n, are in the position shown in black lines-the valves c c are raised, and. the column of water flows in the direction shown by the black arrows the valve o is also open, and a column of water following the lower bucket L, and filling the chamber a. Now reverse the motion of the buckets, or move them downward, and the puppet valves assume the positions in which they are shown in red lines, and the valves c, c, instantly close, charrb'erY 0i below the bucket K, is forced through the passages s, p, to the exit, while the vacuum behind the bucket is being filled for the next operationand thus there is a continuous flow of Water from the well to ill up the vacuum behind the buckets, While the puppets shift at every stroke of the pump so' as to empty one chamber, and ll the other, and thus keep up a continuous How through the pump.

As the stem 7c, simply carries up its valve m to its seat against the bucket, and it drops by t-he Weight of the Water upon it, it is obvious that that valve need not of necessity be permanently attached to the stem, but may be loose from, and. still be carried up by the stem. Nor is it material that that valve should be a disk valve, for it may be a ball valve.

Having thus fully described the nature and object of my invention what I claim and the vv'ater in the l therein yas. new and desire to secure by Letlters Patent is- 1. Dividing the pump cylinder into two chambers a, a, by the division valve seat plate b, with its valves opening upward, and uniting them by the water way E, substan tially as herein described, and for the purpose set forth.

2. I also claim the puppet valves m, n, connected to, and operating with, the buckets K, L, in the two chambers so that while they move with said buckets, they shall have action independent of them as set forth.

3. I also claim in combination with the hollow piston, and'stem passing through it, the causing of the upper valve m to close upward against its bucket substantially as JOI-IN H. YOUNG.

v herein described.
